Funny, Cool & Rare Videos: How To Boost Your Cellphone Signal

I don't want to damage my phone.

yeah and after that your gonna have a cell phone as big as my boots :P XD

not all phone has that small hole in the back. furthermore my provider has good coverage

there are other alternatives to boost the phone signal, like those sticky antenas that you put them on the back of the phone, under the battery

I still don't understand the point behind those stickers. They don't always work. I think they just psychologically make you think they work. I mean it's increased the signal of a Motorola phone but then when I tried it in my 3G Japanese phones, it made the signal worse..... :( no ideas....
